DESCRIPTION

The L4941 is a three terminal 5V positive

regulators available in TO-220, TO-220FP and

of industrial and consumer applications. Thanks to

its very low input/output voltage drop, these

devices

are

particularly

suitable

for

battery

powered equipments, reducing consumption and

prolonging battery life. It employs internal current

limiting, antisaturation circuit, thermal shut-down

and safeareaprotection.
